Asahipak GS-320 HQ is a multimode column and capable of analyzing typical "Umami" (nucleic acids), i.e. IMP, GMP and AMP (nucleotide), and all of their metabolites with simple isocratic elution. The main characteristic of the column is that the nine components(IMP, GMP, AMP and their respective nucleotides, purine bases and pyrimidine bases) are completely separated for approximately 35 minutes and elute in order of nucleotides, nucleosides, purine bases and pyrimidine bases.
